For most publishers that are old school the bread and butter or call it the heart. Is the ink on the rollers of their printing press's and those printing press's that supports their brick and mortar business and employee's.

The E-book supports none of that, all the publisher needs is a computer and in general nothing else.

Paper and ink supports the staff in the layout and press rooms and without those two items being consumed by the printing press's and helping the employe's in their livelihoods. A large part of the staff would be out of work.

So in a way the e-book compared to the printed page is of lower priority. Because some of those publishing houses do care for their staffs and in some ways are like family's. In a convoluted way. E-books in a way can be seen as stepchild's compared to ink and paper book production. (No disrespect to any stepchildren out there)
